Abstract
Water-dilutable polyurethane dispersions comprising structural units derived from polyisocyanates A, polyols B having a number-average molar mass Mof at least 400 g/mol, compounds D that contain at least two groups reactive towards isocyanate groups and at least one group capable of anion formation, low molar mass polyols E that do not carry any further groups reactive towards isocyanate groups, compounds G that are monofunctional towards isocyanates or contain active hydrogen of different reactivity and that are different from the compounds E, characterised in that the polyols B contain a mass fraction of polycarbonate polyols Bof at least 85%, and the use thereof in coating compositions
